Please refer to fig. 1. The utility model discloses a press cutting shaping duplex position all-in-one, include: the paper cutting machine comprises an outer body 1, a reverse cutting part 2 arranged on the outer body 1 and a die cutting part 3 arranged on the outer body 1, wherein a paper conveying part 4 for conveying paper is arranged between the reverse cutting part 2 and the die cutting part 3, and the reverse cutting part 2 and the die cutting part 3 are used for respectively and independently processing the paper.

Generally, after the printing and embossing processes of a packing box product are completed, the paper reverse cutting and die cutting processes can be processed and completed at a die cutting position of equipment, in the processing process, the front surface and the back surface of the paper are stressed, namely the front surface of the paper is subjected to die cutting force, and the back surface of the paper is subjected to reverse cutting force. The reverse cutting means that under the action of reverse cutting force of the device, a blade of the device extrudes the paper from the reverse side of the paper, so that indentations are generated on the surface of the paper, the cigarette case can be easily folded in the packaging process of the device, but the pressure cannot be too large, or the paper is easily crushed. Therefore, the process split of die cutting and reverse cutting is processed by two stations, and the processing difficulty of paper is greatly reduced. The control system of the application can be composed of PLC modules, the control driving is realized by electrically connecting the PLC modules with each component, and the application of the PLC modules is the prior art which can be easily thought by a person skilled in the art, so the application of the PLC modules is not detailed here.

Meanwhile, in the process of paper offset printing, according to the process requirements of the cigarette case, side positioning lines are added at the specified die cutting positions of the paper, and cross positioning lines are added at the reverse cutting positions. Increase printing cross location line and side location line and can guarantee the paper in the location of anti-cutting and cross cutting in-process, and then guarantee that the counter-knife is fixed at paper processing position with the die-cutting rule, and only divide into two stations with cross cutting and anti-cutting, just be convenient for accurate location, otherwise carry out the anti-cutting simultaneously and be difficult to fix a position according to the location line with cross cutting work. Therefore, on one hand, the situation that the position of the counter-cutter and the position of the die-cutter are not fixed in the machining engineering and the stability of the batch of products is poor is avoided, on the other hand, the judgment difficulty of accuracy of the machining position of the counter-cutter and the die-cutter in the machining process is also reduced by adding a positioning line.

As a preferred embodiment, the paper feed station 4 comprises several drive rollers. The paper can be conveyed to the die cutting part 3 from the reverse cutting part 2 smoothly through the rotation of the transmission roller shaft, and the paper cannot be broken or bent in the transportation process.

In a preferred embodiment, the reverse cutting part 2 is provided with a paper feeding part 5 at one end far away from the paper feeding part 4, and the die cutting part 3 is provided with a paper collecting part 6 at one end far away from the paper feeding part 4.

In a preferred embodiment, the paper feeding section 5 and the paper delivery section 6 each include a lift table 7. The lifting platform 7 can send the paper into the reverse cutting position 2 through the lifting of the lifting platform 7 under the control of the PLC, and the paper discharged from the die cutting position 3 is stored through the descending of the lifting platform 7 so as to be taken away by workers.

As a preferred embodiment, the die cutting part 3 includes a die cutting knife for performing die cutting on the paper, and a first tooth row for conveying the paper after the die cutting to the next station, and the reverse cutting part 2 includes a reverse cutting knife for performing reverse cutting on the paper, and a second tooth row for conveying the paper after the reverse cutting to the next station.

As a preferred embodiment, the cutting edge of the counter-knife is arc-shaped with the radius of 0.15-0.25 mm. Set up the sharp degree that has reduced the counter-knife edge department on the one hand like this, under the same counter-cutting pressure, to a great extent has reduced the product and has appeared exploding the line defect at the counter-cutting in-process (exploding the line and indicating that the paper counter-cutting position appears the crushing condition because the counter-cutting force is too big), can deepen the counter-cutting line vestige simultaneously, make the product indentation vestige more mellow and more mellow, the box piece later stage packing of being convenient for, on the other hand, the counter-cutting department blunts, make the counter-cutting back, more easily break away from out from the paper counter-cutting indentation after the counter-cutting embedding paper, greatly reduced the risk that the paper was torn.

As a preferred embodiment, the reverse cutting part 2 also comprises a sponge strip which is arranged at a position 2-3mm away from the cutting edge of the reverse cutting knife. The reason why the sponge is needed to be padded is that the paper adopted by the soft package hardened product of the yellow crane storied building is the single-side coated white cardboard with 170 grams per square meter (the cigarette standard is more than 220 and 230 grams per square meter), the high stiffness, the bursting strength, the smoothness, the whiteness and the excellent printability are required, the paper surface is required to be flat, and no streak, spot, unevenness and warping deformation are required. And because the paper is thinner, lead to the paper to appear warping easily, and after the processing, when the paper was taken to the delivery position through the gripper bar, because the reason of the countercut cutter embedding paper, the paper was torn easily when being pulled by the gripper bar, so must lay up the sponge in countercut position 2, the paper is a reverse elasticity after the countercut, makes the paper break away from the countercut cutter smoothly.

As a preferred embodiment, the thickness of the sponge strip is 1-2 mm. Because reverse cutting and cross cutting technology go on simultaneously in the equipment now, adopt 5mm thick sponge more, because sponge thickness is too big, in cross cutting pressure and reverse cutting pressure coextrusion in-process, the sponge warp inconsistent, can lead to the paper to appear warping differently, make the cigarette case of producing have certain degree deformation, seriously influence product shaping effect, the paper warp simultaneously and differs, make die-cutting sword and reverse cutting sword produce the deviation in the position of processing on the paper, thereby lead to the unilateral defect to appear in the product, unilateral defect refers to because paper reverse cutting position and cross cutting position do not correspond the deviation that appears, thereby lead to in the cigarette case packaging process, the printing pattern on the box piece is not in cigarette case surface's centre position deviation one side. After the thickness is changed to 1-2mm, because the reverse cutting processing of the equipment does not receive the effect of die cutting force relative to the front side of the paper in the prior art, and the opening of the reverse cutter is made into an arc shape with the radius of 0.15-0.25mm, the smooth glass opening of the paper can be ensured. And because the sponge thickness is thinner, in the reverse cutting process, the deformation of the paper is greatly reduced due to the deformation of the sponge, the deformation of the paper is reduced, on one hand, the packaging adaptability of the product is improved, on the other hand, the deviation of the reverse cutting position of the reverse cutter on the paper is greatly reduced, and the reverse cutting position of the reverse cutter is ensured to be within the range of the requirement of the production process.
